Thisinforms the Litespan common control assemblythat the H2TU-C has been removed from its slot,after which the common control assembly beginslooking for the reinsertion of the line card.Reinsertion any earlier than this may temporarilylock the H2TU-C into a nonfunctional statebecause the common control assembly will notsend the AHDSL2 equipment type code to theH2TU-C line card.ComplianceThis product is intended for installation in restrictedaccess locations only and in equipment with a Type“B” or “E” enclosure.WARNINGUp to –200 VDC may be present ontelecommunications wiring. The DSX-1interface is intended for connection tointra-building wiring only. Ensure chassis groundis properly connected.This product provides span powering voltage(negative only with respect to ground, –190 VDCnominal, GFI protection < 5 mA) and meets allrequirements of Bellcore GR-1089-CORE (Class A2)and ANSI T1.418-2002. This product is NRTL listedto the applicable UL standards.Table 2 shows the compliance codes for this product.ProvisioningProvisioning of the H2TU-C is through the craftinterface on the Maintenance and Test Interface (MTI)card either via TL1 commands or the Litecraft ProGraphical User Interface (GUI).
